BRAKE AND MOTOR CONTROLLING MECHANISM FOR MOTOR-VEHICLES.

SPECIFICATION forming part of Letters Patent No. 781,789, dated February '7, 1905. finalisation filed July 5,1904. Serial No. 2l5,272.

To r/.// 1117/10/10 it but concur/1 Be it known that I, CnAnLns SGIIMII)1,2I citi- Mechanism for i\Iotor-Yehiclcs, of which the following is a specification, reference being i matic means forellectmg this result. wluch is bad therein to the accompanying drawings.

struction of the brake and power-transmission mechanism whereby the application of the brake automatically releases a clutch in the transmission mechanism, said clutch being also operable independently of the brake.

In the drawings, Figure I is a plan of a motor-vehicle to which my improvement is applied. Fig. is a section through a portion ofthetransmission mechanism, illustrating its l The construction of parts is such that in the 0 connection with the brake mechanism. Fig. 3 is a transverse section; and Fig. ii: is a view similar to Fig. 2, showing the parts in ditlerent positions of adjustment.

A is the frame of the vehicle, B is a motor I 5 supported thereon, and (l the drive-shaft.

I) is a trans1nission-shatt extending between the motor and drive-shaft, and E is a clutch for connecting said shaft to the drive-shaft. The clutchshown comprises the fly-wheel u of 0 the engine, which is preferably provided with the annular flange 1/, within whiclris arranged a circular head c, mounted upon the transmission-shaft I). Between the head c and the flange is an expansible ring (l, which is connected through suitable mechanism comprising a pinion c and rack f with a longitudinal slidable sleeve 1/ on the shaft I). This sleeve g is grooved to receive the collar /z, which is pivotally connected to the bifurcated end of v a foot-lever F, 'fulcrumed in the bracket (it on the cross-bar H of the frame. The arrangement is such that by operating the foot-lever F the sleeve 1/ is moved to contract the expansible ring and release the clutch, said clutch 5 being again engaged automatically by the op eration of a spring I when the lever released.

The vehicle is provided with asuitable brake The invention consists in the peculiar coni mechanism, which, as shown, comprises the brake-head J on the axle, connected by the links I( with rock-arms Ii on the rock-shaft M. This rock-shaft is operated by a controllinglever N, by means of which the brake may be set or released. As it is desirable to disconnect the motor from the drive-axle whenever the brake is applied, I have provided autoot the following construction: 0 is a rockarm which is connected to the rock-shaft F of the foot-lever I I is a rock-arm journalcd in the bracket (l and connected by the link Q. with the rock-arm R on the rock-shaft M, to which the lever N is attached. The rock-arm I is connected to the rock-arm S, which swings in the path of the rock-arm U and is adapted to actuate the latter, so as to move the foot-lever I and release the clutch.

initial movement of the lever N and before the brake has been set thereby the rock-arm S will be actuated to move the arm and release the clutch, as just described. During the continued movement of the lever N the lever I is maintained in its releasing position, and this is etlected by providing the rock-arm t) with the segmental portion T, which after the initial movement of the rock-arm b is arranged ctmcentric with the axis of said rockarm, so that the latter is free to move without imparting further movement to the rockarm t). This rock-arm O is, however, held from being returned by the spring I as long as the rock-arm S is in engagement with the segmental portion T.

From the description above given it will be understood that every time the brake is operated the clutch E is released, so as to disconnect the motor from the drive-axle, and upon the releasing of said brake the spring I will automatically reengage the clutch. It will be also understood that the connections which cause this operation of the clutch do not interfere with its independentoperation through the actuation of the foot-lever F.

\Vhat I claim as my invention is I. In a motor-vehicle, the combination with a frame and a motor supported thereon, a drive-axle and a transmission-shaft extending between said motor and said drive-axle, of a clutch for coupling said motor to said trans mission-shaft, a foot-lever for operating said clutch, a brake mechanism, an operating-lever therefor, a connection between said brake-operating mechanism and said foot-lever, whereby the operation of the brake will release said clutch, and means for limiting the movement imparted to said clutch to the initial movement of said brake-operating mechanism.

2. In a motor-vehicle, the combination with a frame and a motor supported thereon, a drive-axle and a transmission-shaft extending between said motor and drive-axle, of a clutch for coupling said motor to transmission-shaft, a footlever for releasing said clutch, a brake mechanism, a rock-arm actuated thereby, an arm on said foot-lever extending into the path of said rock-arm, whereby the operation of said brake will automatically actuate said foot lever to release said clutch, and means for limiting the movement imparted to said clutch to the initial movement of said brake-operating mechanism.

3. In a motor-vehicle, the combination with a frame and a motor supported thereon, a drive-axle, a transmission-shaft extending between said motor and said drive-axle, of a clutch for coupling said motor to said transmission-shaft, a foot-lever for releasing said clutch, a brake mechanism, a rock-arm actuated thereby, and an arm on said foot-lever having a segmental portion and extending into the path of said rock-arm whereby the initial movement of said brake mechanism will arrange said segmental portion concentric with the radius of said rock-arm.

4. In a motor-vehicle, the combination with a frame and a motor supported thereon, a drive-axle and a transmission-shaft extending between said motor and drive-axle, of a clutch for coupling said motor to said transmissionshaft, a foot-lever for releasing said clutch, a brake mechanism, a rock-arm actuated thereby, and an arm on said foot-lever having a segmental portion and extending into the path of said rock-arm whereby the initial movement of said brake mechanism will release said clutch and arrange said segmental portion of said arm concentric With the radius of said rock-arm.

In testimony whereof I affix my signature in presence of two witnesses.
